Application filed September 19, 1900. gerial N 1 0i l (N0 m l- T0 at whom it may concern."

Be it known that 1, CHARLES W. CRAMER, a citizen of the United 'States, residing at Scranton, in the county of Laokawanna and State of Pennsylvania, have invented certain new and useful Improvements in Liquid Dispensing and Measuring Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to pumps designed for use in pumping liquids from vessels or tanks and measuring the amount of liquid pumped.

The object of the invention is to provide an improved pump of this class embodying in its construction means for regulating the amount of liquid pumped, means for pumping liquid from any one of a plurality of tanks, and means for discharging liquid in streams of various sizes.

With these objects in view the invention consists in the improved construction, arrangement, and combination of parts hereinafter fully described and afterward specifically claimed.

In the accompanying drawings, Figure 1 represents a vertical longitudinal section through a measuring-pump constructed in accordance with the present invention. Fig. 2 represents a front elevation of the same, portions being broken away andshown in section. Fig. 3 represents a top plan view of the pump. Fig. 4 represents a bottom plan view of the pump-cylinder; Fig. 5, an enlarged detail View through a portion of a pumpcylinder and an outlet-Valve arranged in an upwardly-extending discharge-pipe. Fig. 6 represents a detail View showing the delivery end of the discharge-pipe illustrated in Fig; 5 and illustrating the manner in which the revolnble nozzle can be applied to the same. Fig. 7 represents a detail sectional View through the top of the cylinder, showing the means for controlling the amount of liquid' which shall be pumped. Fig. 8 is a vertical central section through the registering mechanism. Fig. 9 is a front elevation of the same. Fig. 10 is a detail View in elevation of one of the gear-wheels in the said register. Fig. 11 is a detail fragmentary view of a portion of the registering mechanism, showing the ratchetof a segment 8.

wheel employed therein; and Fig. 12 is a detail view showing the wheel for operating the revoluble plate or disk in the bottom of the pump-cylinder and illustrating the indication-marks thereon. i

In embodying these features into practical form I form the pump with a cylinder 1, which is preferably provided with attaching lugs or flanges 2 2, so that it may be screwed or bolted to any suitable support, as at. Within the cylinder 1 is arranged a piston, as 5, which is carried by the lower end of a reciprocating piston-rod 6. The piston-rod 6 is designed to pass through an opening in the cover of the cylinder and is provided upon one side with a series of grate-teeth, forming a rack, as at '7, adapted to engage with the gear-teeth The segment 8 is rigidly secured to an operating rock-shaft 9, which finds suitable bearings in the top of inder 1. The rock-shaft extends outside the bearings and is bent to form part of a crankarm, as at 10. The other portion of the crankarm is formed by an inclosing sleeve 11,wl1ich telescopes upon the end of the arm 10 and is bent at its outer end and provided with an operating-handle 12. The. sleeve 11 is providedwith a head, as at 13, which fits upon the arm 10 and is rigidly secured to the sleeve 11. A set-screw, as 14, adapted to extend through the collar 13 and engage notches, as at 15 15, formed in the arm 10, permits the said crank-arm to be adjusted to difierent lengths. By this means a greater or less power may be applied to the pumping n1echanisin, as found desirable, the leverage being increased or diminished by the adjustment of the sleeve 11. The segment 8 preferably travels in the casing 16, arranged upon the cover of the pump, so that no foreign substance or dirt can get into the pump-cylinder. The base or bottom plate 17 of the pump-cylinder 1 is formed with a series of openings, as at 18 18,whioh are adapted to be connected. by as many suction-pipes 19 19 with a number of supply-tanks, as 20. The supplytanks 20 may be arranged at anydesired distance from the pump-as, for instance, in handling inflammable liquids the tank may be placed in the ground outside of a house or store and be connected with the pump by a suction-pipe 19, so that the liquid will not the cyl-- have to be stored in the building, but can be pumped and measured whenever desired.

The suction-pipes of course can be led in different directions to different tanks. The

suction -pipes are secured tightly at their ends to openings formed in the bottom plate 17 ofthe pump. Immediately inside the bottom plate 17 and tightly mounted thereon is a revoluble plate 21, which is adapted to move over the said bottom plate, but in snug contact therewith. This plate or disk 21 is provided with a single opening, asat 22,whieh 'is 'of'a suitable size to register withthe openings in the base or bottom platglY. By turntag this plate so that its opening 22 is brought over the suction-pipe which leads to the receptacle containing the desired fluid the pump will operate to draw the liquid only from that particular tank. When it is desired to draw liquid from another tank the plate is turned "'so'that the opening 22./will coincide with its suction-pipe, By this construction the same pump can be used for drawing liquids from any one or a number of tanks and can be quickly connected with any of them. In order to actuate the said revoluble plate 21, I form a bevel-gear, as 23, on the under face of the same and so arrange it as to mesh with a bevel-gear 24, carried by a shaft 25 outside the pump. The shaft 25 finds suitable bearings, as at 26, in lugs or projections formed upon the base-plate 17 of the pump. The

outer end of the shaft 25 projects slightly beyond the pump-cylinder 1 and is provided with an operating-wheel 27, so arranged as to be easily turned by hand. By this structure the inner revolving plate 21 can be readily turned at any time. This hand operating wheel 27 is preferably provided upon its outer face with marks or projections, as at 28, which may be arranged to coincide with a corresponding pointer or mark 29, formed upon the side of the pump. By this arrangement the position of the revolving plate 2l inside the can can always be determined, and by bringing a certain 'number upon the wheel 27 opposite the projection or pointer 29 on the cylinder the opening 22 can be arranged opposite the mouth of the suction-pipe corresponding with said number. The tanks are preferably closed and are provided with suitable inlet-pipes, as at 30, by which they may be filled at any time. The suction-pipes 19 extend preferably to a point near the bottom of the tanks and may be provided with any suitable valve, as at 31, for preventing a backflow of the liquid from the said pipes into the tank- It is desirable oftentimes to make these tanks quite'snugly closed, and in this instance it is necessary to provide an air-inlet valve, as at 32, of any suitable construction, so that when liquid is drawn from the tank all tendency to a vacuum therein will be avoided and the pumping operation will not be retarded.

In connection with the pump thusdescribed, the manner of mounting and forming the delivery-nozzle for the same forms an i1npor= taut feature of the present invention. The

nozzle is usually formed, as illustrated in Fig.

l of the drawings, so as to project slightly to one side of the said cylinder. The nozzle casing or casting, as 33, is preferably screwthreaded at its upper edge and fits into the corguided by a spider, as at 38, arranged within the casing 33. This nozzle is also provided with a circular track or guideway, as at 39, which extends entirely around the casing and ring 40 is provided with a series of dischargenozzles, as 41 41. These nozzles are arranged at different points upon the ring, and by turning the ring upon the guideway 39 any the discharge-opening of the casing 33. These nozzles may be made of different sizes or diameters, so that when a large receptacle is to be filled a large nozzle may be used for and when a receptacle having a smaller opening or inlet is to be filled a smaller nozzle may be employed for concentrating the liquid in a smaller stream. In using such a ring as just described it is necessary of course to bind the same snugly against the casing 33,

said casing and the nozzle used. For this purpose I form an extension, as at 42, upon same and the ring 40. Upon the ring and extending toward the projection 42 is a smaller or shorter projection, as 43. The ends of these projections do not quite meet and are provided with screw-threads upon their outer 1 15 surfaces for the short distances which are adapted to be engaged by a sleeve, as 44. The threads of the opposing projections are oppositely arranged, and the sleeve 44 is provided upon its inner surface with oppositely- 12o arranged threads on each end thereof for engaging the'threads on the said projections. By turning the sleeve the ring 40 may be forced upwardly away from the casing at its upper portion, which will operateto draw its lower portion against the open end of the nozzle. The ring may then be turned to bring any one of the delivery-spouts opposite to the said opening' The said sleeve may be responding screw-threaded opening formed 75.

This 80 the valve, the said stem being preferably 85 is adapted to engage a revoluble ring 40. The 0 one of thenozzles may be brought opposite 5 more quickly discharging the fluid or liquid, too

so that there will be no leakage between the the upper side of the casing 33 between the no tightened at any time should any of the spouts leak, but is sufficiently loose to permit of the turning of said ring. Anyone or more of the nozzles may be provided with external screw-threads, as at 45, if desired, so

that the nozzle may be connected with suitable piping for delivering the liquid at a greater distance from the pump. An important feature of my improved nozzle also is means supplied for cleaning the same. The projections 42 and 43 are preferably made hollow, and a cock or valve, as 46, is placed in the projection 42, so as to control the passage-way throught to it. This cook 46 is normally kept closed, so that the suction of the pump for drawing liquids from the suctionpipes 19 is not destroyed. When it is desired to clean out the chamber of the valve within the nozzle, the cook 46 is opened and the pump-piston being raised at such a time will draw air in through the openings in the extensions 42 and 43 and draw the same into the pump-cylinder as instead of drawing liquids from the suction-pipes 19. After the pump-cylinder has thus been filled by air by closing the cock 46 and depressing the piston the air may be forced through the valvechamber past the valve and out the nozzle, so as to thoroughly clean the same and rid it of any liquids. The nozzle-casing 33 may be provided with a projection or hook, as at 47, if desired, upon which buckets or other handled receptacles may be hung for receiving the liquid discharged.

As seen in Fig. 5 of the drawings, it is sometimes desirable to carry the discharge or delivery spout upwardly above the pump-cylinder. In this instance the delivery-spout 48 preferably extends upwardly outside the pump cylinder, and a valve chamber is formed, as at 49, with a suitable valve 50 mounted therein, adapted to perform the same function as the valve 35, heretofore described. In this arrangement of the device it is necessary to modify the direction of the spout 48, so that the revolving nozzle may be placed thereon. This is illustrated in Fig. 6 of the drawings, where it will be seen the deliveryspout is turned outwardly from the pump and carries at its outer end the nozzle-chamber 33 and the nozzle-ring 40, as before described and illustrated. In order to measure the amount of liquid pumped, I provide a device upon the top of the pump-cylinder l which is adapted to engage a segment 8 and control the amount of its movement. This device comprises a lever 50, pivoted to a suitable stud 51 upon the cover of the pump. This lever is preferably covered by a casing 52, formed by a raised portion off the cover of the pump. The lever 50 is thus protected from being clogged by the accumulation of dirt or other foreign substances. The other end of the lever is provided with an operating-handle 53, which extends outside the easing 52, the lower end of the said handle travcling in a curved slot, as 54, formed in the said casing. The inner end of the lever 50 projects into the casing 16 and is adapted to be arranged in the path ofa series of lugs or stops 55,secured to one face of the segment 8. These lugs 55 are arranged in different radial disof ratchet-teeth 62, while tances from the axis of the shaft 9, so that when the lever 50 is moved into the path of one of said lugs it will not be in the path of any of the others and will not come into contact with any of the others. These lugs are also arranged at different distances from one end of the curved rack formed on the segment 8, so that they will permit the said rack to be moved at certain stated distances, according to the lug which is engaged by the lever 50. It will be seen that the lever 50 can be quickly set to engage the proper lug upon the segment 8, so that any desired quantity of liquid can be pumped by the operation of the pistons 6. To guide the operator of the lever in properly locating the positions of the lever, a stud or pin 50 is secured thereto, which is adapted to engage depressions or recesses on the under surface of the cover and arranged so as to hold the lever opposite the saidlugs 55. In connection with the said pump I also desire to employ a registering mechanism for keeping an accurate account of the amount of liquid passing through the pump. For this purpose I arrange upon the cover of the cylinder 1 a simple contrivance comprising a gear-wheel, as 56, arranged within a casing 57 and so located as to have its teeth mesh with rack-teeth 58 upon one side of the piston 6. The gear-wheel 56 is mounted upon a spindle or shaft 59, also arranged in the casing 57, and upon the said shaft to one side of the said gear-wheel 56 is a second wheel 60. This wheel 60 is formed upon its face which is adjacent to the gear-wheel 56 with .an annular projection 61. The projection 61 has formed upon its inner upon its outer periphery a second series of ratchet-teeth, as 63, are formed, which are arranged to extend in the same direction as the teeth 62. The inner ratchet-teeth 62 are adapted to be engaged by a spring-controlled pawl 64, carried by a gear-Wheel 56, so that when the gear-wheel turns in one direction the pawl 64 will actuate or engage one of the inner teeth 62 and force the wheel 60 around; but.

when the gear-wheel 56 is turned in the opposite direction the pawl will merely slip over the opposite teeth and obtain a new hold upon the wheel 60'. In order to prevent any back movement of the wheel 60, a springpawl 65 is arranged upon the inner surface of the casing 57, so as to come into contact with the teeth 63. This will permit the wheel 60 to be drawn in one direction by the pawl 64,

but will prevent its being turned backwardly again upon the opposite movement of the gearwheels 56. The shaft 59 also carries a series of indicating-disks, as 65 65, which are connected and operated by each otherin the same manner as the indicating-disks of an ordinary bicycle-cyclometer. Thisformsnonovelfeature of the present invention, and therefore need not be explained further. The figures upon the peripheries of the said disks 65 are arranged opposite the opening 66 in the casperiphery a series;

. cut that by the use of my improved pump 1 ing 57, so that the figures will show there and can be read from the outside. The figures are also arranged upon the periphery of the wheel and show through an opening 67, formed in the said casing. The indications upon this wheel are adapted to indicate measurements of smaller quanties, while the indices on the wheel are adapted to keep an account of the aggregate liquid dispensed.

From the above description it will be apparam enabled to pump liquids from diiferent receptacles and'from different distances and that I can accurately measure the quantity of liquid discharged, as well as keep a reeprd of the quantity of liquid pumped from time to time. The parts are simple in construction and. easy of manipulation and form a structure which will be found very valuable in handling large amounts of liquid.
